Answer:

B; There is only one (x,y) solution and y is negative

Step-by-step explanation:

First, I graphed the two equations. Attached is an image of the equations graphed. Next, I looked for overlapping points. Wherever the two points overlap, there is a solution. When looking at the graph, we can see the lines overlap at only one point, (0,-1). Since y is negative, the answer must be B; there is only one (x,y) solution and y is negative.

Discuss measures that can be taken to develop the spirit of hard work

Answer:

A = 20%

B = 80%

Step-by-step explanation:

200/1000 people said Lombardi's, or:

since 1,000 = 100

and 200 = 20

then we can simplify this to

20/100 0r 20%

and if 100 people to the survey and 20/100 said Lombardi's,

that means 80% must have said Patsy's, because,

100 - 20 is the 80 percent of people who didn't vote for Lombardi's, and since Patsy's is the only other option, that means the other 80% voted for Patsy's.

So

20% said Lombardi's

and

80% said Patsy's!

to be honest, I think I like Patsy's more as well.

EXPLANATION:

According to what the exercise shows us, we must do a division of fractions; then we have that the whole table is divided into 6/4

Therefore, Catherine's federal income tax withheld each week is $0.

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

Here,

To calculate the federal income tax withheld for Catherine Hall, we need to use the weekly payroll tables provided by the IRS. Here are the steps:

Determine Catherine's gross pay for the week. Her gross pay is her total earnings before any deductions are taken out. In this case, her gross pay is $208.35.

Determine Catherine's adjusted gross pay. This is her gross pay minus any pre-tax deductions, such as contributions to a 401(k) or health insurance premiums. Since we don't have any information about pre-tax deductions, we can assume that Catherine's adjusted gross pay is the same as her gross pay.

Determine Catherine's taxable income. To do this, we need to subtract her standard deduction and personal exemptions from her adjusted gross pay. Since Catherine is single and claims 2 allowances, her standard deduction is $12,550 and her personal exemption is $4,350 ($4,350 x 2 = $8,700). Therefore, her taxable income is:

Adjusted gross pay - (standard deduction + personal exemptions)

= $208.35 - ($12,550 + $8,700)

= $-4,915.65 (negative value means there is no taxable income)

Use the IRS weekly payroll tables to find the federal income tax withheld for Catherine. Since her taxable income is negative, her federal income tax withheld will be $0.

Answer:

\(\bold{f(x) = 375(2.5)^{-x}+ 33}\)

Step-by-step explanation:

An exponential function of form f(x) = ba^(-x) + c has a horizontal asymptote of y = c as x approaches infinity, and a y-intercept of (0, b + c). We can use the given information to set up a system of equations and solve for the unknowns.

The horizontal asymptote is given as y = 33, so we have:

c = 33

The y-intercept is given as (0, 408), so we have:

b + c = 408

Substituting c = 33, we get:

b + 33 = 408

b = 375

So the function we're looking for is of the form:

\(\bold{f(x) = 375a^{-x}+ 33}\)

To find a, we use the fact that the function passes through P(2, 93):

93 = 375a^(-2) + 33

60 = 375a^(-2)

a^2 = 375/60

a^2 = 6.25

a = \(\sqrt{6.25 } =2.5\)

Therefore, the exponential function that satisfies the given conditions is:

\(\bold{f(x) = 375(2.5)^{-x}+ 33}\)

32 people came in blue cars and 6 people came in red cars

Step-by-step explanation:

Technically, all 48 people came in red or blue cars, but I'm assuming that's not what the question is asking.

To find how many people came in blue cars, we do 2/3*48 which is equal to 32 people.

To find how many people came in red cars, we do 1/8*48 which is equal to 6 people.

Considering the descriptions, angle CEB is found to be 93 degrees

Angle CEB is calculated by investigating the sketch attached

From the sketch, angle CEB and angle AEC are supplementary angles

and angle AEC is given to be 87 degrees.

Supplementary angles are angles that have their sum equal to 180 degrees.

hence In the problem, we have that

angle CEB + angle AEC = 180 degrees

where

angle AEC = 87.

substituting the value into the equation will result to

angle CEB + 87 = 180

angle CEB = 180 - 87

angle CEB = 93 degrees

We can therefore say that angle CEB = 93 degrees

The values of the constants m and c include the following:

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + c

Where:

Since the point P(-7, 2) is mapped onto P' (3, -11) by the reflection y = mx + c, we can write the following system of equations;

2 = -7m + c    ...equation 1.

-11 = 3m + c    ...equation 2.

By solving the system of equations simultaneously, we have:

2 = -7m - 3m - 11

Answer: A

The polynomial has roots at \(x=-4, -2, 4\).

So, the equation should have factors of \((x+4), (x-2), (x-4)\).

This eliminates everything except for A.

The expression that is always equivalent to sin x when 0° < x < 90° is (1) cos (90° - x). Option 1

To understand why, let's analyze the trigonometric functions involved. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. Since we are considering angles between 0° and 90°, we can guarantee that the side opposite the angle will always be the shortest side of the triangle, and the hypotenuse will be the longest side.

Now let's examine the expression cos (90° - x). The cosine of an angle is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. In a right triangle, when we subtract an angle x from 90°, we are left with the complementary angle to x. This means that the remaining angle in the triangle is 90° - x.

Since the side adjacent to the angle 90° - x is the same as the side opposite the angle x, and the hypotenuse is the same, the ratio of the adjacent side to the hypotenuse remains the same. Therefore, cos (90° - x) is equivalent to sin x for angles between 0° and 90°.

On the other hand, options (2) cos (45° - x) and (3) cos (2x) do not always yield the same value as sin x for all angles between 0° and 90°. The expression cos x (option 4) is equivalent to sin (90° - x), not sin x.

Option 1 is correct.

The transformation T that transposes every matrix is indeed linear.

Let's analyze each of the extra properties:

(a) T² = identity transformation: This is true. When you transpose a matrix twice (apply T twice), you get the original

matrix back.

Step 1: Apply T to a matrix M to get its transpose M'.

Step 2: Apply T to the transpose M' to get (M')' which is equal to M.

(b) The kernel of T is the zero matrix: This is true. The kernel of T consists of all matrices M such that T(M) = 0. Since the

transpose of a zero matrix is still a zero matrix, the kernel of T only contains the zero matrix.

(c) Every matrix is in the range of T: This is true. Given any matrix M, there exists another matrix M' such that T(M') = M.

This is because T(M') = M implies M' = T(M), so the transpose of any matrix M can be found by applying T to M.

(d) T(M) = -M is impossible: This is false. It is possible for T(M) = -M in the case of skew-symmetric matrices. A skew

The acceleration of the bullet while in the barrel is 184335.7 m/s^2.

First, let us understand the acceleration:

Any action where the velocity changes are said to it as acceleration. There are only two ways to accelerate: altering your speed or altering your direction, or altering both. This happens because velocity is both a speed and a direction.

We are given;

The length of the barrel of the rifle is 0.983 m.

The speed of the bullet is 602m/s.

From the third equation of motion, we know that,

v^2 = u^2+ 2aS

Initial velocity, u=0

Final velocity, v = 602m/s.

Distance, S = 0.983 m.

Substitute the given values in the above formula,

v^2 = u^2 + 2aS

(602)^2 = 0 + 2 * a * 0.983

1.966a = 362404

a = 362404/1.966

a =  184335.7 m/s^2.

Thus, the acceleration of the bullet while in the barrel is 184335.7 m/s^2.

The size of the largest interior angle of the field is 69.86°

The law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles.

Given that, a triangular field has boundaries of lengths 170m, 195m and 210m, we need to find the size of the largest interior angle of the field,

We know that, angle opposite to the largest side is largest,

Therefore,

The largest angle is opposite is 210 m side, (say c)

Using the cosine rule,

210² = 170²+195²-2(170)(195)cosC

CosC = 170²+195²-210² / 2(170)(195)

CosC = 22825 / 66300
